Community-based economics is when people join together as a group to buy goods or services from other people and businesses. This helps to support local businesses, keep money in the community, and make sure that everyone in the community is getting the goods and services they need. For example, if a community wants to buy food from local farmers, they can join together to buy that food from the farmers, instead of buying from big companies that are far away. This helps to keep money in the community and make sure that everyone in the community has enough food to eat.
